If you follow me on the Okierover Facebook Page you read that I needed to replace my oil sump gasket. And as I predicted the weather did NOT cooperate. It stopped snowing at 1030 that morning but the wind was blowing 20-30 mph all day. It was very chilly in the garage.
If you are from Oklahoma or drive a domestic automobile (Chevy, Ford, Dodge, just kidding no one drives a Dodge) you can translate oil sump to oil pan.
I had trouble with the term too. Try Googling “oil pan gasket” when your British motor car has all their parts listed as “oil sump”. The same thing happens when you are searching the RAVE manual looking for an oil pan. Thankfully when I ordered the part from Rovah Farm it was easy to find.
Back to the leak, the Big White Bus has recently been leaving a nice puddle of oil when she comes to a stop. I know all the jokes about British cars and leaks. If you don’t see a leak, it’s probably dry. Well, I don’t care for leaks. I do my best to find the leaks and eliminate them. Like the steering box, it leaks like a sieve. I should have a rebuilt unit next week. And I will have it installed by the end of that Saturday. That will be the last of the petroleum based fluid leaks. It only took me 3 (three) years!
The source of the leak? the oil sump gasket or to be more specific, the LACK of a gasket. I am the second owner of this motor. As you can see below, someone used Permatex Ultra Gray for a gasket. First, Ultra Black should be used, not Gray, and there should be a cork gasket completing the seal. If you have done this I’m not criticizing, I’m just pointing out now you probably know why it’s leaking.
My oil pan sump had to be removed and serviced. There was rust and chipped paint and what was left of the “gasket” had to be removed prior to putting a new one in. I was surprised that something that has had so much leaked oil on it could rust, but it did.
I got the trusty angle grinder out and hooked up a wire wheel and scraped off the rust and the factory paint (black). The challenge was getting the oil and grime off. I used brake cleaner, a lot of rags, and in the final stage before painting I used some pre-paint grease remover.
While I had it off I cleaned some of the grime and muck out of the sump. I used a flat razor scraper. I was careful to make sure I left no “chunks” in there. Short of a sand blaster there was no way to get all the baked on muck out of there. My sand blaster cabinet is not big enough.
The sump was ready to be painted. I got the Mar-Hyde Self Etching Primer from inside the house where it was being stored at a temperature that allowed it to be used. I painted the pan with the first coat and then brought the pan into the house and into my office to dry. I gave it an hour to dray and when back out to clean up the underside of the motor. I also swapped out the last poly bushings on the radius arms.
I put the second coat of paint on and after some waiting I started to put it all back together. The first thing that is required is getting the Permatex Ultra Black gasket maker on and letting it set up. I did this in my office. I wasn’t even sure if it would setup in my garage at 30 degrees Fahrenheit. Once it set up I put the cork gasket on and lined it up. The Permatex acts like an adhesive at least enough to secure the gasket from moving during install.
The next challenge is to get the sump back in place and bolted up to the block. Take your time and don’t rush. The cork gasket can slip and if you break it, you are done. After it is in place you bring the bolts up to snug. The manual calls for you to tighten it to specific torque settings. The idea here is that you don’t crush the gasket.
From the manual you can see that is not a lot of torque needed. I don’t have a torque wrench that I could get my 13mm sockets on. You have to use narrow walled sockets, etc… in short my tool chest is inadequate for this. So I was careful when I was tightening them. A note here, the rear bolts are not labeled but I assumed it was the ones on the row nearest the transmission tunnel.
I finished up the oil change and and then the moment of truth came. I got the oil up to temperature and watched for leaks. None were found. I drove the Big White Bus to church the next day and still no leaks. I’m going to mark that down as a success. I will of course be watching it for the next week.
On the Okierover Difficulty Scale this job is a 2 (two). You will have the oil sump off, you will get oily and dirty (and not the good kind). You also have to remove the sway bar to get the sump out. If you aren’t going to clean it up you can skip the removal and just clean it up while under the engine.
Thanks for reading and Happy Rovering.
